# DayCalc vs Calculy

The clearest difference is ads: Calculy at none against DayCalc's shown. Calculy also leads on monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.7). DayCalc's advantage is ratings volume (128 vs 1). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. DayCalc sells 4 one-off in-app purchases and Calculy sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Calculy holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: DayCalc has 128 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 87% of DayCalc's written reviews are positive against 91% of Calculy's.

DayCalc ships an update every 3 weeks, Calculy every 2 weeks. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
